This invention relates to heaters, and it more particularly relates toan improved heater of the reector type.

f An object of the invention is to provide a heater of this characterhaving a perfect .circulation of air, profperly distributed around theburner thereo ysa .A still further object of the invention is to provideair ducts orperforations through the walls of the heater in suchrelation to the burner and to the heatdeeetors with the heater, as toprovide, heated air properly distributed within vthe heater, so that theradiation will be equallized'around t-he heater. y

Gther objects and advantages `may be recited hereinafter' and in theclaims.

In the accompanying drawings which4 form a part of this application,Figure 1.

is a perspective View of my improved heater, certain portions beingbroken away, so as to disclose the interior arrangement, and, Fig. 2 isa vertical sectional view through the frontand back walls of the heaterembodyingmy improvement.

eferringmore particularly to the drawings in which similar referencecharacters designate corresponding parts throughout the several views, lprovide a stove body com risinga metal casing or box consisting of sidewalls 5, rear wall or back 6, an upper front wa1l7, a vlower frontwall 8yand a top 9. The stove body is provided with ordinary legs 10, wherebyan' air space is provided thereunder.

j The front part of the heater is provided with an opening between theportions 7 and. extendin approximately entirely across the body o theheater. The heater is also provided with side linings 11 and a cor- Irugated reflector plate 12, preferably of' copper uof copper-placedsheet metal. The side linings may be secured to the body by any propermeans. The reflector plate is preferably secured to the lower frontportion 8, by rivets, bolts or the like 13,` being also secured, at itslateral edges, to the rear and lower edges of the side plates 11.Instead of the reiector plate being secured at its top to the rear wall6, as in ordinary heaters of this character', an air passage 14 is.pro-v vided therebetween, so that air may pass from the air space underthe heater, up-

kward through the air passage 14.` To the upper' 'portions of the sides5 is secured a substantially horizontal deflector plate 15, beingslightly inclined upwardly toward the rear wall, and being curvedupwardly at its rear portion. A forwardly extending de'- fiector plate16 is secured to the rear wall, curving forwardly therefrom, over therear end of the first said deflector plate. p.

An air passage 17 is provided between the top 9 and the deflector plate16, an air passage or draft opening 18 being provided between thedeflector plates 15 and 16. y

A burner pipe 19, is supported by the side walls 5 in thewell knownmanner, lava tips or jets 2O being secured to the burner pipe andconstituting a part of the gas burner,

said gas burner being adapted to connect' with a gas supply, through themedium of a connecting member 21, a valve 22 of ordinary constructionbeing provided for regulating the flow of gas.

The upper front wall 7 extends below the level of the gas burner. Whenthe gas is turned on and lighted, air enfers the heater through the.open front below the portion 7 and supplies oxygen to aid combustion ofthe gas. However, if no other source of air supply were provided, thecombustion would be incomplete, as this air supply would have the effectof forcing the flame up against' the defiector plates 15 and 16, therebyexcluding air from the upper portion of the flame, so that a part 0f thesmoke or unconsumed products of combustion would be deposited upon thedefiector plate, as soot, the other part of the smoke passing throughthe air passage 18 and out into the room being heated. This smoking andsootlng in heaters, of ordinary construction, is welll known to be veryobjectionable; and 1n or.4 der toovercome this objection, ,E provide aAseries 'of apertures or perfor-ations 23,

through the side walls 5, said apertures being arranged in approximatelyhorizontal .seriesabove the level of the burner. I also the heated airand products ofcombustion' may pass from the passage 17, when desired,and I may also provide the top portion of the heater witlroutletapertures 27, above the de'lector plate 15, to auxiliate the passage ofheated air from the heater, so that a considerable volume of air will becontinually passing through the heater while in use.

The objects of the perforations, above the burner, are to completelysurround the flame with air, so that complete combustion of the gas willresult; and to temper the heat adjacent to the walls of the heater, sothat unsightly discoloration ot" the walls, by excessive heat, isavoided. Moreover, by thus supplying a large quantity .oit moderatelyheated air, the objectionable feature of intensely heated air risingrapidly to the ceiling is avoided; the advantageous difference betweenthe operation of my improved heater and of ordinary heaters, being quiteobvious, since the. moderately heated air spreads through 'the inhabitedportion of the room, tempering the cooler air in the room; while moreintensely heated air above the heads of the inhabitants, does not mix ortemper the lower strata of air in the room, nor does it perform anydesirable function.

ln opera-tion, the burner being lighted, air enters through the main.front opening and through the perforations 9A, and together with theforce of the from -the burner jet carries the flame in an approximatelyhori-A zontal direction toward the rear wall of the heater; whereupon,air passing upward through the passage' 1e and inward through theperfor-ations 25, supplies oxygen to the. terminus of the flame anddirects 1t upwardlythrough the passage 18; and so the a-ir, from theseveral openings and perforations, after absorbing heat from the Haine,passes out through the several openings above the detlector plane.

lt will be seen that l have provided a heater ot this character which isfully capable ot attaining the foregoing objects, andA in athoroughlypractical and eilicient manner.,

I do notilimit my invention to the exact details of construction,combination and arrangement of parts as herewith described andillustrated, but my invention may only be limited by a reasonableinterpretation of the following claims.

What I claim is':

1. The combination in a gas stove, of a hollow body having side wallsand a rear wall and a front wall, said front wall having a relativelylarge front opening therethrough, a horizontal gas burner supported bythe side walls and being located nearthe front wall above said frontopening and adapted to direct a flame rearwardly, 'a forward deflectorplate joined onto the front 'wall above said front` opening and extendinrearwardly therefrom, said front wall being provided with a horizontallydisposed series of apertures communicating with the interior portion ofthe stove below said deflect-or plate and above said burner fordirecting a. mitigated current of air between said detlector plate andsaid flame, saidA burner being spaced apart from said forward deflectorplate to a suiiicient extent for preventing flame contact with saidplate, and an inclined rear defleetor plate secured on the rear wall.and extending upward. and forward so as to overhang the forwarddeiiector plate and to provide a narrow passa e therebetween said sidewalls bein rovided with outlet openings above the rearwardly extendingdei'lector plate and' infront of the forwardly extending deiector plate,and said rear wall being provided with perforations slightly below therear deiiector plate, whereby an air `current is establisjhed betweensaid plate andthe dame and products of combustion from the burner.

2. The combination in a gas stove, of a hollow body having side wallsanda' rear itY wall and a front wall, said front wall beingi provided witha. relatively large front opening, a burner supported near the Jfrontwall on a plane above said front opening and extending horizontallyacross said body and adapted to throw a flame toward the rear wall, adeflector plate joined onto the front wall above the front opening andabove the burner andiextending rearwardly, said front wall and said sidewalls being provided 'with a substantially horizontal series ofapertures on a plane above the burner and below the delector plate forsupplying a current ot y air bet-Ween said deflector plate and said ameand thereby .preventing flame contact with 4said detlector plate, aninclined delector plate secured on the rear wall Aand -extendingupwardly and forwardly therefrom' lin such relation to the first saiddeflector plate Vas to provide a passage therebetween forythecoinbustion products, said rear wall being providedwith'perforations sghtly beow the forwardly extending der name to thisspecification in the presence of eclnr plain, sa body pmvded with twosubscribing Witnesses. ,Quiet openings on a ane above the rearl T1 T fWwfdly extending elec'tor plate and in PQRTE Ml' BRADLEY' 5 iront of theowardly extending deector Witnesses:
